Answer:

The roots are -5, 1.

Step-by-step explanation:

$f(x) = x^2 + 4x - 5$

The roots of a function are also the Ox intercepts, so basically we're finding when is the function equal to '0'.

$x^2 + 4x - 5 = 0\\(x-1)(x+5) = 0\\x_1 = 1, x_2 = -5$

Answer:

20.

$18.40.

Step-by-step explanation:

The mean number of people = (12+19+17+26+26)/5

= 100/5

= 20.

Karmin's original hourly rate = 480/30

= $16 per hour.

With a 15% rise it is 16 * 1.15

= $18.40 / hour.

If y varies directly as x^2 and y=12 when x=2, find y when x=5

Shkiper50 [21]

$y=ax^2\\\\y=12\ \ \ and\ \ \ x=2\ \ \ \Rightarrow\ \ \ 12=a\cdot 2^2\ \ \ \Rightarrow\ \ \ a= \frac{4}{12}= \frac{1}{3} \\\\y=\frac{1}{3} x^2\\\\x=5\ \ \ \Rightarrow\ \ \ y=\frac{1}{3} \cdot5^2=\frac{25}{3} =8\frac{1}{3}$
